在导出excel时,发现中文的标题乱码，试了N种编码方式，开始总是试图转为utf-8,gb2312,gbk,没想到转为iso-8859-1中文乱码的问题解决了

fileName = new String(fileName.getBytes(),"iso-8859-1");
  response.setCharacterEncoding("gb2312");
  response.reset();
  response.setContentType("application/OCTET-STREAM;charset=gb2312");
  response.setHeader("pragma", "no-cache");
  response.addHeader("Content-Disposition", "attachment;filename=\""
    + fileName + ".xls\"");// 点击导出excle按钮时候页面显示的默认名称
  workbook = Workbook.createWorkbook(response.getOutputStream());
